The enantioselective environmental behavior and toxicological effects of pyriproxyfen in soil
Journal of Hazardous Materials, 2019We synthesized nine pyriproxyfen (PYR) metabolites and developed a chiral residual analysis method for PYR with its metabolites in five soils using ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Soil degradation research showed that higher organic matter content and bigger soil particle size were conducive to the ...

Formulation of pyriproxyfen, a juvenile hormone mimic, for tsetse control
Medical and Veterinary Entomology, 1990ABSTRACT. A topical dose, in 1 uJ acetone, of 0.02 |xg 2‐[l‐methyl‐2‐(4‐phenoxyphenoxy) ethoxy] pyridine, the juvenile hormone mimic pyriproxyfen (S‐31183, Sumitomo Chemical Co.), caused an adult female tsetse, Glossina morsitans morsitans Westwood, to produce non‐viable ...

The effect of pyriproxyfen on the motoric activity of rat intestine - In vitro study
Environmental Pollution, 2018The application of pyriproxyfen (PPF) to drinking water and constant exposure of the whole population to this insecticide is an unprecedented action on a world scale and presents a new and serious challenge for toxicology. The aim of the study was to evaluate the potential effect of PPF on the intestine muscle activity.

Field Evaluation of Resistance to Pyriproxyfen in Bemisia tabaci (B Biotype)
Journal of Economic Entomology, 2007We determined effects of aerial sprays of the insect growth regulator pyriproxyfen on sweetpotato whitefly, Bemisia tabaci (Gennadius) (B biotype), in Arizona cotton (Gossypium spp.) fields. We measured survival for males and females from a susceptible strain and a laboratory-selected resistant strain, as well as for hybrid female progeny from crosses ...

We used computer simulations to examine evolution of resistance to the insect growth regulator (IGR) pyriproxyfen by the sweetpotato whitefly, Bemisia tabaci (Gennadius), biotype B [=Bemisia argentifolii (Bellows & Perring)]. Consistent with trends seen in cotton (Gossipyium spp.) fields in Arizona and Israel, results suggest that evolution of ...

Effects of Pyriproxyfen Treatment on the Insect Growth Rates
Entomological Research, 2011Larvae of Bombyx mori fed on the mulberry leaves treated with pyriproxyfen extended the larval duration. The silkworm on the third day of the fourth instar fed pyriproxyfen 10‐6 concentration extended the fifth instar duration over 20 days and was not able to spinning silk.
